ATM and Metformin Response
These results were generated in a CLIA-approved laboratory as part of the Coriell Personalized Medicine Collaborative research study. Results take into account 1 genetic variant in the ATM gene, known to influence treatment response to metformin. Metformin is sold under the brand names Fortamet®, Glucophage®, Glucophage XR®, Glumetza®, Riomet®. This report reflects this participant’s predicted treatment response based on genetic testing but does not reflect whether they are currently taking metformin.
The CPMC has a genetic counselor who is available to assist with report interpretation at no charge. For questions please contact us at
cpmcgc@coriell.org
or by phone at 888-580-8028. Participants may schedule an appointment with our board certified genetic counselor by logging into their web portal account and clicking on “request an appointment”. For general information about the CPMC please visit our website

This research report includes all data included in the clinical report as well as supplemental drug specific interpretations and educational material. Please see the report that follows for the official clinical report.
Your combination of genetic variant results is listed below in yellow.

1Other variants, not currently included in this CPMC test may influence this result and interpretation.
-
Your genetic variant result is associated with an increased likelihood of treatment success when taking metformin.
-
Individuals with at least 1 copy of the rs11212617 ‘C’ variant are more likely to reach a target HbA1c level of less than 7% when taking metformin compared to individuals who have no copies of the ‘C’ variant.
-
Hemoglobin A1c (HbA1c) is a blood test that measures average level of blood sugar (glucose) over the past 3 months. This test is used to monitor diabetes control.

Genetic Risk Factors
Genetic variants, or changes, in a gene called ATM can affect the likelihood that treatment with metformin will be successful.
Some people with certain genetic variants may have an increased likelihood of treatment success with metformin.
Non-Genetic Risk Factors
Many factors affect how your body responds to medications.
Non-genetic factors include: diet, lifestyle, medical history and interactions between medications.
Gene Affecting Metformin Response:
ATM
ATM Gene Variant
There is one common variant in the ATM gene known to influence the likelihood of treatment success with metformin. We all have 2 copies of every gene; when possible, you will have an ATM gene result with two letters (Variant=C, Reference/Normal=A).
Example: ATM-AC

The following foods, vitamins, and supplements are known to interact with metformin:
Alcohol
- Avoid drinking alcohol while taking metformin.
- Drinking alcohol while taking metformin increases the risk of developing a condition called lactic acidosis.
- Get help immediately if you have any of the following symptoms of lactic acidosis: weakness, increasing sleepiness, slow heart rate, cold feeling, muscle pain, shortness of breath, or stomach pain.
Gymnema sylvestre
- Avoid taking the herb gymnema sylvestre while taking metformin.
- Taking gymnema sylvestre while taking metformin may cause your blood sugar to become too low.
- Tell your doctor if you experience symptoms of low blood sugar, such as: sweating, rapid heartbeat, and dizziness.

Result Limitations
- This result alone does NOT predict your total response to metformin.
- Other factors such as body weight, various health conditions, and other medications may impact an individual’s response to metformin.
- There may be other genetic variants within the ATM gene which influence response to metformin but are not included in this test.
- There may be other genetic variants in the ATM gene for which response to metformin has not been documented and/or validated in multiple studies.
- There may be genetic variants in other genes that influence response to metformin
- This result reflects published data available at the time this gene-drug pair was approved by the CPMC Pharmacogenetics Advisory Group (September 2013). The information provided may change as new scientific information becomes available.
- Although rare, it is possible that you may receive an incorrect result; 100% accuracy of reported results cannot be guaranteed.
- Occasionally, we will be unable to interpret one or more gene variants. In this case you will not receive a result for those variants and in some cases your drug response cannot be interpreted. It is expected that you will receive results for about 95% of variants approved by the
Pharmacogenetics Advisory Group (PAG)
and
Informed Cohort Oversight Board (ICOB).
- Every effort will be made to provide you with risk information based on your reported race/ethnicity. However, data may not be available for all races/ethnicities. Please see your individual results to determine which race/ethnicity the data is based on.
Test Limitations
DNA-based testing is highly accurate, however there are many sources of potential error including: mis-identification of samples, rare technical errors, trace contamination of PCR reactions, and rare genetic variants that interfere with analysis. There may be other variants in the ATM gene that are not included in this test, that influence the response to metformin. This test or one or more of its components was developed and its performance characteristics determined by the Coriell Institute for Medical Research. It has not been approved by the Food and Drug Administration (FDA). The FDA has determined that such approval is not necessary. The Coriell Institute is regulated under the Clinical Laboratory Improvement Amendments (CLIA) of 1988 as qualified to perform high-complexity testing.
Test Methodology
Saliva samples were collected using Oragene DNA Collection Kits (DNA Genotek) and DNA was extracted manually according to the manufacturer’s instructions or automatically using a DNAdvance Kit (Agencourt). Purified DNA was quantified using UV absorbance at 260 nm. One microgram of the resulting DNA from each sample was used as template in the Affymetrix DMET Plus GeneChip assay. Data analysis was performed using Affymetrix DMET Console software.
